run_wizard() ends with error

[erinaldi]

Hi,

I was looking to play with this package and I encountered an issue with run_wizard()
First of all I have julia v1.9.1 and I have an environment where only LatticeQCD.jl v.1.0.6 has been installed.
Then I start the REPL and run using LatticeQCD; run_wizard().
If I keep pressing Enter using all the default values, the process ends correctly and I can then run run_LQCD("my_parameters.toml") .

The first problem here is that the wizard ends also explaining that one can run run_LQCD(params_set) directly and that is not working. There is no variable params_set in the session.

The second problem arises if I run the wizard in expert mode and I try to setup a pure gauge SU(2) run.
Here is the entire process as I did it, ending with the error:

I tried a couple of times with different "expert" mode configurations and the wizard was never able to terminate successfully.

What is going wrong here?

[erinaldi]

If I repeat the process without Gradient Flow measurements (select No at that step), the wizard ends successfully creating an input file.

Moreover, there is no option to choose a different gauge action for Yang-Mills while the README states that any action is supported (e.g. Symanzik).

I am sorry for delaying responding. I will see this issue.

I fixed run_wizard().
In the previous version, 1.0.6, has the bug for determining a parameter for the energy density measurement in the gradient flow. Now in v1.0.7, I think the bug was removed.
